Investigation of Engineered Cementitious Composite for Culvert Repair: Extended Abstract

Corrugated metal pipe culverts are distressed at the inverts because of abrasion and corrosion. Concrete has been used to repair the inverts in thicknesses of about 4 inches. Environmentalists object to such thicknesses because of restriction to the water flow. This study investigated engineered cementitious composite (ECC) in thicknesses of 1 inch or less above the crest of the corrugated metal pipe. ECC contains short polyvinyl alcohol fibers and exhibits very tight numerous cracks that prevent the infiltration of solutions from within the pipe. ECC is used in the invert and along the side where water rises most of the time. Biaxial geogrids were used to reinforce the thin ECC and to keep the concrete from sliding along the sides. Initially in the laboratory in small batches, ECC with locally available materials and regular sand was developed and placed in culvert samples that had geogrid attached. Then, as a preparation for actual culvert repairs, ECC was prepared in a truck mixer and placed in large culvert samples at a district office of the Virginia Department of Transportation. Since some of the culverts are coated with asphalt, in an actual deteriorating asphalt-coated culvert, a 6-foot section was repaired to ensure that ECC could perform well with minimal cracking. With the geogrid and the screws, ECC was attached to the metal culvert, and after weeks of observation, it appeared to stay in place.
